Same here, the bridges do not match the novel height of the upperdeck jetways.
And, I know I am annoying, the height is still not the double of the "normal" jetway, making it basically still impossible to stack two jetways on top of each other (as at gate E67 in Zurich). It only works without that the lower jetway glitches into the upper one when using the Thyssenkrupp upper deck and the other brand lower deck, which then does not look right. Anyway, I wait for what comes in the near future, currently I have anyway no chance to test the upperdeck jetways, as I have no A380 or 747.
